BACKGROUND OF THE INVENTION Field of the Art

The disclosure relates to the field of computer management, and more particularly to the field of cybersecurity and threat analytics.

Discussion of the State of the Art

On Aug. 4, 2016, United States government's DEFENSE ADVANCED RESEARCH PROJECTS AGENCY (DARPA)™ hosted an event in 2016 called the Cyber Grand Challenge, aimed at creating an automatic defense system for network defense and vulnerability detection and patching. During the event numerous teams and individuals competed to develop a system which could automatically detect vulnerabilities and exploits in software systems, develop a patch, and deploy the patch within a finite amount of time, in an effort to produce a highly robust system to defend software systems from a variety of possible exploits and malicious attacks. The competition was partially successful, with the submitted systems from each team competing automatically in a capture-the-flag style competition, and the competition in its entirety demonstrated that fully autonomous network defense and exploitation is possible. No team's submission completed the competition with 100% success in identifying vulnerabilities and exploits, and as of yet no such system is deployed for large scale or commercial applications in automated analysis and defense of networks and network-connected devices. Malware of today is continually being advanced in the area of memory scanning, to evade detection from current anti-virus and antimalware software, and continually advancing and evolving network and system defense techniques are required in order to keep up with the pace of advancement of malware both today and in the future. Even until this competition, no system existed even for research applications which could reliably identify and patch vulnerabilities and exploits in software systems and networks before malware took advantage of said vulnerabilities in the software. It is commonly the case that vulnerabilities and exploits in software are only found out and then patched some time after they are taken advantage of, falling out of view of the system developers before the issue is made use of by malicious actors, for example the Heartbleed exploit present in many OpenSSL systems until patched in 2014, only shortly after the vulnerability was publicly disclosed.

What is needed is a system and methods for sandboxed malware analysis and automated patch development, deployment and validation, and further, a system which can use state-of-the-art machine learning techniques and artificial intelligence paradigms to evolve its understanding of malware analysis to help keep pace with the advancement of malware in the world.

DETAILED DESCRIPTION

The inventor has conceived, and reduced to practice, a system and methods for sandboxed malware analysis and automated patch development, deployment and validation.

One or more different aspects may be described in the present application. Further, for one or more of the aspects described herein, numerous alternative arrangements may be described; it should be appreciated that these are presented for illustrative purposes only and are not limiting of the aspects contained herein or the claims presented herein in any way. One or more of the arrangements may be widely applicable to numerous aspects, as may be readily apparent from the disclosure. In general, arrangements are described in sufficient detail to enable those skilled in the art to practice one or more of the aspects, and it should be appreciated that other arrangements may be utilized and that structural, logical, software, electrical and other changes may be made without departing from the scope of the particular aspects. Particular features of one or more of the aspects described herein may be described with reference to one or more particular aspects or figures that form a part of the present disclosure, and in which are shown, by way of illustration, specific arrangements of one or more of the aspects. It should be appreciated, however, that such features are not limited to usage in the one or more particular aspects or figures with reference to which they are described. The present disclosure is neither a literal description of all arrangements of one or more of the aspects nor a listing of features of one or more of the aspects that must be present in all arrangements.

Headings of sections provided in this patent application and the title of this patent application are for convenience only, and are not to be taken as limiting the disclosure in any way.

Devices that are in communication with each other need not be in continuous communication with each other, unless expressly specified otherwise. In addition, devices that are in communication with each other may communicate directly or indirectly through one or more communication means or intermediaries, logical or physical.

A description of an aspect with several components in communication with each other does not imply that all such components are required. To the contrary, a variety of optional components may be described to illustrate a wide variety of possible aspects and in order to more fully illustrate one or more aspects. Similarly, although process steps, method steps, algorithms or the like may be described in a sequential order, such processes, methods and algorithms may generally be configured to work in alternate orders, unless specifically stated to the contrary. In other words, any sequence or order of steps that may be described in this patent application does not, in and of itself, indicate a requirement that the steps be performed in that order. The steps of described processes may be performed in any order practical. Further, some steps may be performed simultaneously despite being described or implied as occurring non-simultaneously (e.g., because one step is described after the other step). Moreover, the illustration of a process by its depiction in a drawing does not imply that the illustrated process is exclusive of other variations and modifications thereto, does not imply that the illustrated process or any of its steps are necessary to one or more of the aspects, and does not imply that the illustrated process is preferred. Also, steps are generally described once per aspect, but this does not mean they must occur once, or that they may only occur once each time a process, method, or algorithm is carried out or executed. Some steps may be omitted in some aspects or some occurrences, or some steps may be executed more than once in a given aspect or occurrence.

When a single device or article is described herein, it will be readily apparent that more than one device or article may be used in place of a single device or article. Similarly, where more than one device or article is described herein, it will be readily apparent that a single device or article may be used in place of the more than one device or article.

The functionality or the features of a device may be alternatively embodied by one or more other devices that are not explicitly described as having such functionality or features. Thus, other aspects need not include the device itself.

Techniques and mechanisms described or referenced herein will sometimes be described in singular form for clarity. However, it should be appreciated that particular aspects may include multiple iterations of a technique or multiple instantiations of a mechanism unless noted otherwise. Process descriptions or blocks in figures should be understood as representing modules, segments, or portions of code which include one or more executable instructions for implementing specific logical functions or steps in the process. Alternate implementations are included within the scope of various aspects in which, for example, functions may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those having ordinary skill in the art.

Definitions

As used herein, a “swimlane” is a communication channel between a time series sensor data reception and apportioning device and a data store meant to hold the apportioned data time series sensor data. A swimlane is able to move a specific, finite amount of data between the two devices. For example a single swimlane might reliably carry and have incorporated into the data store, the data equivalent of 5 seconds worth of data from 10 sensors in 5 seconds, this being its capacity. Attempts to place 5 seconds worth of data received from 6 sensors using one swimlane would result in data loss.

As used herein, a “metaswimlane” is an as-needed logical combination of transfer capacity of two or more real swimlanes that is transparent to the requesting process. Sensor studies where the amount of data received per unit time is expected to be highly heterogeneous over time may be initiated to use metaswimlanes. Using the example used above that a single real swimlane can transfer and incorporate the 5 seconds worth of data of 10 sensors without data loss, the sudden receipt of incoming sensor data from 13 sensors during a 5 second interval would cause the system to create a two swimlane metaswimlane to accommodate the standard 10 sensors of data in one real swimlane and the 3 sensor data overage in the second, transparently added real swimlane, however no changes to the data receipt logic would be needed as the data reception and apportionment device would add the additional real swimlane transparently.

Conceptual Architecture

FIG. 1 is a diagram of an exemplary architecture of a system for the capture and storage of time series data from sensors with heterogeneous reporting profiles according to a preferred aspect of the invention 100. In this embodiment, a plurality of sensor devices 110 a-n stream data to a collection device, in this case a web server acting as a network gateway 115. These sensors 110 a-n can be of several forms, some non-exhaustive examples being: physical sensors measuring humidity, pressure, temperature, orientation, and presence of a gas; or virtual such as programming measuring a level of network traffic, memory usage in a controller, and number of times the word “refill” is used in a stream of email messages on a particular network segment, to name a small few of the many diverse forms known to the art. In the embodiment, the sensor data is passed without transformation to the data management engine 120, where it is aggregated and organized for storage in a specific type of data store 125 designed to handle the multidimensional time series data resultant from sensor data. Raw sensor data can exhibit highly different delivery characteristics. Some sensor sets may deliver low to moderate volumes of data continuously. It would be infeasible to attempt to store the data in this continuous fashion to a data store as attempting to assign identifying keys and store real time data from multiple sensors would invariably lead to significant data loss. In this circumstance, the data stream management engine 120 would hold incoming data in memory, keeping only the parameters, or “dimensions” from within the larger sensor stream that are pre-decided by the administrator of the study as important and instructions to store them transmitted from the administration device 112. The data stream management engine 120 would then aggregate the data from multiple individual sensors and apportion that data at a predetermined interval, for example, every 10 seconds, using the timestamp as the key when storing the data to a multidimensional time series data store over a single swimlane of sufficient size. This highly ordered delivery of a foreseeable amount of data per unit time is particularly amenable to data capture and storage but patterns where delivery of data from sensors occurs irregularly and the amount of data is extremely heterogeneous are quite prevalent. In these situations, the data stream management engine cannot successfully use strictly single time interval over a single swimlane mode of data storage. In addition to the single time interval method the invention also can make use of event based storage triggers where a predetermined number of data receipt events, as set at the administration device 112, triggers transfer of a data block consisting of the apportioned number of events as one dimension and a number of sensor ids as the other. In the embodiment, the system time at commitment or a time stamp that is part of the sensor data received is used as the key for the data block value of the value-key pair. The invention can also accept a raw data stream with commitment occurring when the accumulated stream data reaches a predesigned size set at the administration device 112.

It is also likely that that during times of heavy reporting from a moderate to large array of sensors, the instantaneous load of data to be committed will exceed what can be reliably transferred over a single swimlane. The embodiment of the invention can, if capture parameters pre-set at the administration device 112, combine the data movement capacity of two or more swimlanes, the combined bandwidth dubbed a metaswimlane, transparently to the committing process, to accommodate the influx of data in need of commitment. All sensor data, regardless of delivery circumstances are stored in a multidimensional time series data store 125 which is designed for very low overhead and rapid data storage and minimal maintenance needs to sap resources. The embodiment uses a key-value pair data store examples of which are Riak, Redis and Berkeley DB for their low overhead and speed, although the invention is not specifically tied to a single data store type to the exclusion of others known in the art should another data store with better response and feature characteristics emerge. Due to factors easily surmised by those knowledgeable in the art, data store commitment reliability is dependent on data store data size under the conditions intrinsic to time series sensor data analysis. The number of data records must be kept relatively low for the herein disclosed purpose. As an example one group of developers restrict the size of their multidimensional time series key-value pair data store to approximately 8.64×10⁴ records, equivalent to 24 hours of 1 second interval sensor readings or 60 days of 1 minute interval readings. In this development system the oldest data is deleted from the data store and lost. This loss of data is acceptable under development conditions but in a production environment, the loss of the older data is almost always significant and unacceptable. The invention accounts for this need to retain older data by stipulating that aged data be placed in long term storage. In the embodiment, the archival storage is included 130. This archival storage might be locally provided by the user, might be cloud based such as that offered by Amazon Web Services or Google or could be any other available very large capacity storage method known to those skilled in the art.

Reliably capturing and storing sensor data as well as providing for longer term, offline, storage of the data, while important, is only an exercise without methods to repetitively retrieve and analyze most likely differing but specific sets of data over time. The invention provides for this requirement with a robust query language that both provides straightforward language to retrieve data sets bounded by multiple parameters, but to then invoke several transformations on that data set prior to output. In the embodiment isolation of desired data sets and transformations applied to that data occurs using pre-defined query commands issued from the administration device 112 and acted upon within the database by the structured query interpreter 135. Below is a highly simplified example statement to illustrate the method by which a very small number of options that are available using the structured query interpreter 135 might be accessed.

SELECT [STREAMING|EVENTS] data_spec FROM [unit] timestamp TO timestamp GROUPBY (sensor_id, identifier) FILTER [filter_identifier] FORMAT [sensor [AS identifier] [, sensor [AS identifier]] . . . ] (TEXT|JSON|FUNNEL|KML|GEOJSON|TOPOJSON);

Here “data_spec” might be replaced by a list of individual sensors from a larger array of sensors and each sensor in the list might be given a human readable identifier in the format “sensor AS identifier”. “unit” allows the researcher to assign a periodicity for the sensor data such as second (s), minute (m), hour (h). One or more transformational filters, which include but a not limited to: mean, median, variance, standard deviation, standard linear interpolation, or Kalman filtering and smoothing, may be applied and then data formatted in one or more formats examples of with are text, JSON, KML, GEOJSON and TOPOJSON among others known to the art, depending on the intended use of the data.

FIG. 2 is a diagram of an exemplary architecture of a business operating system 200 according to a preferred aspect. Client access to the system 205 both for system control and for interaction with system output such as automated predictive decision making and planning and alternate pathway simulations, occurs through the system's highly distributed, very high bandwidth cloud interface 210 which is application driven through the use of the Scala/Lift development environment and web interaction operation mediated by AWS ELASTIC BEANSTALK™, both used for standards compliance and ease of development. Much of the business data analyzed by the system both from sources within the confines of the client business, and from cloud based sources, also enter the system through the cloud interface 210, data being passed to the analysis and transformation components of the system, the directed computational graph module 255, high volume web crawling module 215 and multidimensional time series database 220. The directed computational graph retrieves one or more streams of data from a plurality of sources, which includes, but is in no way not limited to, a number of physical sensors, web based questionnaires and surveys, monitoring of electronic infrastructure, crowd sourcing campaigns, and human input device information. Within the directed computational graph, data may be split into two identical streams, wherein one sub-stream may be sent for batch processing and storage while the other sub-stream may be reformatted for transformation pipeline analysis. The data is then transferred to general transformer service 260 for linear data transformation as part of analysis or decomposable transformer service 250 for branching or iterative transformations that are part of analysis. The directed computational graph 255 represents all data as directed graphs where the transformations are nodes and the result messages between transformations edges of the graph. These graphs which contain considerable intermediate transformation data are stored and further analyzed within graph stack module 245. High volume web crawling module 215 uses multiple server hosted preprogrammed web spiders to find and retrieve data of interest from web based sources that are not well tagged by conventional web crawling technology. Multiple dimension time series database module 220 receives data from a large plurality of sensors that may be of several different types. The module is designed to accommodate irregular and high volume surges by dynamically allotting network bandwidth and server processing channels to process the incoming data. Data retrieved by the multidimensional time series database 220 and the high volume web crawling module 215 may be further analyzed and transformed into task optimized results by the directed computational graph 255 and associated general transformer service 250 and decomposable transformer service 260 modules.

Results of the transformative analysis process may then be combined with further client directives, additional business rules and practices relevant to the analysis and situational information external to the already available data in the automated planning service module 230 which also runs powerful predictive statistics functions and machine learning algorithms to allow future trends and outcomes to be rapidly forecast based upon the current system derived results and choosing each a plurality of possible business decisions. Using all available data, the automated planning service module 230 may propose business decisions most likely to result is the most favorable business outcome with a usably high level of certainty. Closely related to the automated planning service module in the use of system derived results in conjunction with possible externally supplied additional information in the assistance of end user business decision making, the business outcome simulation module 225 coupled with the end user facing observation and state estimation service 240 allows business decision makers to investigate the probable outcomes of choosing one pending course of action over another based upon analysis of the current available data. For example, the pipelines operations department has reported a very small reduction in crude oil pressure in a section of pipeline in a highly remote section of territory. Many believe the issue is entirely due to a fouled, possibly failing flow sensor, others believe that it is a proximal upstream pump that may have foreign material stuck in it. Correction of both of these possibilities is to increase the output of the effected pump to hopefully clean out it or the fouled sensor. A failing sensor will have to be replaced at the next maintenance cycle. A few, however, feel that the pressure drop is due to a break in the pipeline, probably small at this point, but even so, crude oil is leaking and the remedy for the fouled sensor or pump option could make the leak much worse and waste much time afterwards. The company does have a contractor about 8 hours away, or could rent satellite time to look but both of those are expensive for a probable sensor issue, significantly less than cleaning up an oil spill though and then with significant negative public exposure. These sensor issues have happened before and the business operating system 200 has data from them, which no one really studied due to the great volume of columnar figures, so the alternative courses 225, 240 of action are run. The system, based on all available data predicts that the fouled sensor or pump are unlikely the root cause this time due to other available data and the contractor is dispatched. She finds a small breach in the pipeline. There will be a small cleanup and the pipeline needs to be shutdown for repair but multiple tens of millions of dollars have been saved. This is just one example of a great many of the possible use of the business operating system, those knowledgeable in the art will easily formulate more.

FIG. 3 is a system diagram, illustrating the connections between crucial components, according to an aspect of the invention. Core components include a scheduling task engine 310 which will run any processes and continue with any steps desired by the client, as described in further methods and diagrams in the disclosure. Tasks may be scheduled to run at specific times, or run for certain given amounts of time, which is commonplace for task scheduling software and systems in the art. This task engine 310 is then connected to the internet, and possibly to a single or plurality of local Multi-Dimensional Time-Series Databases (MDTSDB) 125. It is also possible to be connected to remotely hosted and controlled MDTSDB's 125 through the Internet, the physical location or proximity of the MDTSDB for this disclosure not being a limiting factor. In such cases as the MDTSDB 125 is not hosted locally, it must also maintain a connection to the Internet or another form of network for communication with the task engine 310. Device endpoints 330, especially Internet-of-Things (IoT) devices, are also by definition connected to the internet, and in methods described in later figures will be used for cybersecurity analysis and risk assessment. The task engine 310 which will perform the scheduling and running of the methods described herein also maintains a connection to the scoring engine 320, which will be used to evaluate data gathered from the analysis and reconnaissance tasks run by the task scheduling engine 310.

FIG. 4 is a system diagram illustrating connections between important components for analyzing software and network-connected endpoints, according to a preferred aspect. A business operating system (OS) 410 operates on a system outlined in FIG. 2, with key components including the OS kernel 411 which is a component common to all operating systems, and on that kernel, aside from other pieces of software for other purposes, are two important engines, a binary file translator 412 and a sandbox simulation environment 413. A binary file translator 412 may convert any given file or set of input data into executable machine code, and a sandbox environment 413 is a simulation environment which may execute machine code in a closed-off environment, similar in purpose to an experiment carried out in a sealed room. This may be done in a variety of ways, including emulator software for specific system architectures and open source code executors. Such an OS 410 would be connected to a database 420, which may be formatted in Structured Query Language (SQL) form, formatted raw text, encrypted text, or noSQL forms, and may be used in conjunction with management software such as APACHE HADOOP™ for increased performance. This connection may be either a direct physical connection, or the OS 410 and database 420 may be located on the same physical machine, or they may be connected over a network 430, including the Internet or other kinds of computer networks. Similarly, a score generation system 440 may be connected to the operating system 410, either through a network 430, or through a direct physical connection, or by operating on the same machine as the operating system 410 itself. This scoring engine is used in later figures to prioritize software vulnerabilities and exploits. A variety of device endpoints 450 may be connected over a network 430 and accessible to the operating system 410, by use of endpoint instrumentation such as OSQUERY™, and these device endpoints may be varied in form, including laptop computers, desktops, mobile phones, and various Internet of Things (IoT) devices. It is possible for only one endpoint 451 to be connected, and it is similarly possible for a multitude of various different endpoints to be connected 452, 453.

FIG. 5 is a method diagram illustrating important steps in detecting and analyzing software exploits or vulnerabilities, according to a preferred aspect of the invention. A file that is targeted for analysis may be translated into executable binary code 510 by use of a binary translation engine 412, and this executable binary code may then be transferred to a sandbox environment 520, 413, for analysis. The specific environment in use may vary depending on the code generated by the binary translation engine 412, including hardware emulators, operating system emulators, and more. The executable binary code is then executed in the simulated environment 530, and the operating system then may examine the executing software for any irregularities 540. Irregularities include activities not normally performed by benign software including memory scanning, and deletion of the executable binary during execution (but the executing code remaining in memory), which are known patterns of malware to avoid detection and elimination. Attempted access of system files, permissions, settings, or network adapters in suspicious ways may also be classified as “irregularities,” though the characterization and scope of what the operating system 410 looks for may grow and change over time as cybersecurity and malware both advance. The operating system may also probe the executing software for vulnerabilities and exploits 550, which will often be known forms of attack, such as the Heartbleed exploit in OPENSSL™, and are known to many skilled in the art of cybersecurity. The types of vulnerabilities and exploits probed for may change and grow as cybersecurity advances as a field. The operating system 410 may then learn new behaviors 560 according to the results of analysis, for example the operating system 410 may probe for the Heartbleed exploit 550 in a piece of software to see if it is prone to that exploit, and if it is, the operating system may be trained look for similar execution patterns in future software analyses to determine if a piece of software is likely to be vulnerable to the same exploit, an example of reinforcement learning 560. This may be achieved in numerous ways common in the art including neural networks, a basic decision weight system, and more, all common concepts in computer science and software development as a whole.

FIG. 6 is a method diagram illustrating the use of advanced endpoint instrumentation to collect data on endpoint devices across a network, according to a preferred aspect. First, the network endpoint must have the instrumentation installed before it can be utilized 610, and some common instrumentations include OSQUERY™ and open source fleet management software including “doorman,” an open source fleet management suite for OSQUERY™ Software such as OSQUERY™ allows devices to be queried and scanned similar to data files or databases, so that property and/or relational data about the device may be scanned easily and swiftly by an authorized user, in this case the business operating system 410. Once a form of instrumentation software is installed onto the endpoints used in the system 610, device data may be remotely queried by the business operating system 620, similar to a database query over the internet. Device data is then sent back to the machine hosting the business operating system 630, which is then analyzed for potential vulnerability profiling 640. For example, certain phones that may be used in this system have various exploits and vulnerabilities that are exclusive to each other, as do many older operating systems for personal computers, and this information would be able to be queried for analysis 640.

FIG. 7 is a method diagram illustrating the prioritization of software flaws and exploits according to a preferred aspect. Vulnerabilities and exploits found in software executed in the sandbox environment 413 are relayed to the scoring engine 440, 710, which may be either a connection over a network 430 or a direct physical connection between only the two machines, or both the scoring engine 440 and operating system 410 may be operating on the same computing device. The vulnerabilities and exploits found in the software execution may then be scored by the scoring engine 720, which will assign a higher risk level to exploits which may involve deleting system critical files, highly evasive code techniques which may evade most forms of antivirus software, and more, using a scoring methodology which may be specified and changed at any time by the user of the software. The scoring methodology may be arbitrary or follow any given set of rules specified by the user of the software, the importance of this being that as cybersecurity and malware advance, the need for a changing and advancing ranking of threats is obvious and immediate what was considered a horrible computer virus 15 years ago may be easily detectable today, and similarly, what is considered incredibly high-risk today may be of no consequence to antivirus software 15 years from now, and therefore be categorized as a low threat to most devices. Regardless, at the time of execution, the scoring engine 440 will then inform the operating system 410 of a ranking of the found vulnerabilities or threats in the executed software 730, ranking the issues found from most dangerous or pressing, to least dangerous or pressing.

FIG. 8 is a method diagram illustrating the basic steps for patching exploits and vulnerabilities in analyzed software, according to an aspect. After receiving a list of exploitable or dangerous behaviors from a simulated piece of software 730, the business operating system 410 will attempt to make any of various changes or limitations implementable at the kernel level to the software's execution 810, to “patch” the vulnerability or threat. Such measures may include techniques such as Address Space Layout Randomization (ASLR), a memory protection process which randomizes the location in computer memory where system executable code is loaded, and measures used to patch undesirable behavior or vulnerabilities may include other techniques including data execution prevention (DEP), which prevents certain sectors of memory from being executed, protecting potentially important system processes from attack. There are a large variety of security measures that may be implemented in an effort to patch software behavior, and the importance of noting that it is to patch behavior is that the system is not analyzing the code itself and re-writing code in software to be permanently patched, but rather it is changing system behavior based on observed software behavior to protect against any behavior that is either vulnerable to exploitation, or is itself malware. If an implemented patch does not solve the undesired behavior or vulnerability in the tested software, and is deemed a failure, then the operating system 410 may learn through reinforcement learning algorithms to try different measures first, if the same behavior occurs during analysis of a different piece of software 830. If the implemented patch or hotfix does stop the undesirable behavior, and is deemed a success, the operating system 410 learns, conversely to the previous situation, that this patch is an effective measure against such behaviors, and will try it sooner than other (either untested or possibly ineffective) measures that it may have tried 820. This patch or enhancement to the software's functionality is then sent to the endpoint 450, 840 which hosted this file or piece of software that was being analyzed, so that the undesired behavior or vulnerability is effectively mitigated.

Hardware Architecture

Generally, the techniques disclosed herein may be implemented on hardware or a combination of software and hardware. For example, they may be implemented in an operating system kernel, in a separate user process, in a library package bound into network applications, on a specially constructed machine, on an application-specific integrated circuit (“ASIC”), or on a network interface card.

Software/hardware hybrid implementations of at least some of the aspects disclosed herein may be implemented on a programmable network-resident machine (which should be understood to include intermittently connected network-aware machines) selectively activated or reconfigured by a computer program stored in memory. Such network devices may have multiple network interfaces that may be configured or designed to utilize different types of network communication protocols. A general architecture for some of these machines may be described herein in order to illustrate one or more exemplary means by which a given unit of functionality may be implemented. According to specific aspects, at least some of the features or functionalities of the various aspects disclosed herein may be implemented on one or more general-purpose computers associated with one or more networks, such as for example an end-user computer system, a client computer, a network server or other server system, a mobile computing device (e.g., tablet computing device, mobile phone, smartphone, laptop, or other appropriate computing device), a consumer electronic device, a music player, or any other suitable electronic device, router, switch, or other suitable device, or any combination thereof.

In some embodiments, processors 13 may include specially designed hardware such as application-specific integrated circuits (ASICs), electrically erasable programmable read-only memories (EEPROMs), field-programmable gate arrays (FPGAs), and so forth, for controlling operations of computing device 10. In a specific embodiment, a local memory 11 (such as non-volatile random access memory (RAM) and/or read-only memory (ROM), including for example one or more levels of cached memory) may also form part of CPU 12. However, there are many different ways in which memory may be coupled to system 10. Memory 11 may be used for a variety of purposes such as, for example, caching and/or storing data, programming instructions, and the like. It should be further appreciated that CPU 12 may be one of a variety of system-on-a-chip (SOC) type hardware that may include additional hardware such as memory or graphics processing chips, such as a QUALCOMM SNAPDRAGON™ or SAMSUNG EXYNOS™ CPU as are becoming increasingly common in the art, such as for use in mobile devices or integrated devices.

Although the system shown in FIG. 9 illustrates one specific architecture for a computing device 10 for implementing one or more of the inventions described herein, it is by no means the only device architecture on which at least a portion of the features and techniques described herein may be implemented. For example, architectures having one or any number of processors 13 may be used, and such processors 13 may be present in a single device or distributed among any number of devices.

Networks 31 may be implemented using any known network protocols, including for example wired and/or wireless protocols.

In addition, in some embodiments, servers 32 may call external services 37 when needed to obtain additional information, or to refer to additional data concerning a particular call. Communications with external services 37 may take place, for example, via one or more networks 31. In various embodiments, external services 37 may comprise web-enabled services or functionality related to or installed on the hardware device itself. For example, in an embodiment where client applications 24 are implemented on a smartphone or other electronic device, client applications 24 may obtain information stored in a server system 32 in the cloud or on an external service 37 deployed on one or more of a particular enterprise's or user's premises.

In some embodiments of the invention, clients 33 or servers 32 (or both) may make use of one or more specialized services or appliances that may be deployed locally or remotely across one or more networks 31.

In some embodiments, variant database architectures such as column-oriented databases, in-memory databases, clustered databases, distributed databases, or even flat file data repositories may be used according to the invention. It will be appreciated by one having ordinary skill in the art that any combination of known or future database technologies may be used as appropriate, unless a specific database technology or a specific arrangement of components is specified for a particular embodiment herein. Moreover, it should be appreciated that the term “database” as used herein may refer to a physical database machine, a cluster of machines acting as a single database system, or a logical database within an overall database management system. Unless a specific meaning is specified for a given use of the term “database”, it should be construed to mean any of these senses of the word, all of which are understood as a plain meaning of the term “database” by those having ordinary skill in the art.

Similarly, most embodiments of the invention may make use of one or more security systems 36 and configuration systems 35. Security and configuration management are common information technology (IT) and web functions, and some amount of each are generally associated with any IT or web systems. It should be understood by one having ordinary skill in the art that any configuration or security subsystems known in the art now or in the future may be used in conjunction with embodiments of the invention without limitation, unless a specific security 36 or configuration system 35 or approach is specifically required by the description of any specific embodiment.
